The use of timelines as a strategy for teaching legislation issues to IT engineering degree students
[EN] A timeline is a graph showing a sequence of events on a particular topic. Among other things, it allows
to visualize a space-time relationship of the most relevant periods of the topic to be addressed. These
timelines have always been valuable teaching strategies. However, with the use of multimedia
resources linked to the timeline such as images or videos, there is a greater possibility that students
will relate the contents to specific objects that will help them in the understanding and memorization of
dates or events.
The course Deontology and Professionalism in the degree of IT engineering at the Universitat
Politècnica de València incorporates contents that enable students to be exposed to issues of
professional practice, ethical conduct and computer legislation. When working on the legislation
aspects, we suggest the use of timelines as a teaching-learning strategy.
Specifically, the Spanish and European chronologies of data protection and intellectual property
legislation are presented as an example. But if we really want to take advantage of this tool, there is
nothing better than involving students in the creation of such timelines. In this way they will be much
more involved and motivated.Fernández-Diego, M.; González-Ladrón-De-Guevara, F.; Ruiz Font, L.; Boza, A. (2021). The use of timelines as a strategy for teaching legislation issues to IT engineering degree students. IATED. 8678-8683. https://doi.org/10.21125/inted.2021.1798S8678868
Photodiodes based in La0.7Sr0.3MnO3/single layer MoS2 hybrid vertical heterostructures
The fabrication of artificial materials by stacking of individual
two-dimensional (2D) materials is amongst one of the most promising research
avenues in the field of 2D materials. Moreover, this strategy to fabricate new
man-made materials can be further extended by fabricating hybrid stacks between
2D materials and other functional materials with different dimensionality
making the potential number of combinations almost infinite. Among all these
possible combinations, mixing 2D materials with transition metal oxides can
result especially useful because of the large amount of interesting physical
phenomena displayed separately by these two material families. We present a
hybrid device based on the stacking of a single layer MoS2 onto a lanthanum
strontium manganite (La0.7Sr0.3MnO3) thin film, creating an atomically thin
device. It shows a rectifying electrical transport with a ratio of 103, and a
photovoltaic effect with Voc up to 0.4 V. The photodiode behaviour arises as a
consequence of the different doping character of these two materials. This
result paves the way towards combining the efforts of these two large materials
science communities.Comment: 1 table, 4 figures (+9 supp. info. figures
Childhood obesity in Singapore: A Bayesian nonparametric approach
Overweight and obesity in adults are known to be associated with increased risk of metabolic
and cardiovascular diseases. Obesity has now reached epidemic proportions, increasingly affecting children.
Therefore, it is important to understand if this condition persists from early life to childhood and if
different patterns can be detected to inform intervention policies. Our motivating application is a study
of temporal patterns of obesity in children from South Eastern Asia. Our main focus is on clustering
obesity patterns after adjusting for the effect of baseline information. Specifically, we consider a joint
model for height and weight over time. Measurements are taken every six months from birth. To allow
for data-driven clustering of trajectories, we assume a vector autoregressive sampling model with a dependent
logit stick-breaking prior. Simulation studies show good performance of the proposed model to
capture overall growth patterns, as compared to other alternatives.We also fit themodel to the motivating
dataset, and discuss the results, in particular highlighting cluster differences. We have found four large
clusters, corresponding to children sub-groups, though two of them are similar in terms of both height
and weight at each time point. We provide interpretation of these clusters in terms of combinations of
predictors
Capital account regulations and the trading system: a compatibility review
This repository item contains a single issue of the Pardee Center Task Force Reports, a publication series that began publishing in 2009 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future. Spanish version produced by the Center for the Study of State and Society, Buenos Aires.
Portuguese version coordinated by Daniela Magalhaes Prates, a contributing author of the report, in collaboration with Ana Trivellato (translator), and Maria Inês Amorozo (graphic designer).This report is the product of the Pardee Center Task Force on Regulating Capital Flows for Long-Run Development and builds on the Task Force´s first report published in March 2012.
The Pardee Center Task Force was convened initially in September 2011 as consensus was emerging that the global financial crisis has re-confirmed the need to regulate cross-border finance. The March 2012 report argues that international financial institutions – and in particular the International Monetary Fund – need to support measures that would allow capital account regulations (CARs) to become a standard and effective part of the macroeconomic policy toolkit. Yet some policymakers and academics expressed concern that many nations — and especially developing countries — may not have the flexibility to adequately deploy such regulations because of trade and investment treaties they are party to.
In June 2012, the Pardee Center, with the Center for the Study of State and Society (CEDES) in Argentina and Global Development and Environment Institute (GDAE) at Tufts University, convened a second Task Force workshop in Buenos Aires specifically to review agreements at the WTO and various Free Trade Agreements (FTAs) and Bilateral Investment Treaties (BITs) for the extent to which the trading regime is compatible with the ability to deploy effective capital account regulations. This report presents the findings of that review, and highlights a number of potential incompatibilities found between the trade and investment treaties and the ability to deploy CARs. It also highlights an alarming lack of policy space to use CARs under a variety of FTAs and BITs—especially those involving the United States. Like the first report, it was written by an international group of experts whose goal is to help inform discussions and decisions by policymakers at the IMF and elsewhere that will have implications for the economic health and development trajectories for countries around the world
European regulators' views on a wearable-derived performance measurement of Ambulation for Duchenne Muscular Dystrophy regulatory trials
Abstract Development of novel therapies for Duchenne muscular dystrophy (DMD) are driving the need for more efficient ways of detecting changes in disease- progression in DMD [1] . However, medicines' approval must be based on outcome measures that are acceptable from a regulatory perspective. In this article, European regulators provide an update on the recent regulatory consideration of a new endpoint (Stride Velocity 95th Centile (SV95C)) that could be used in therapeutic DMD trials. This new endpoint aims to quantify a patient's ambulation directly, reliably and continuously in a home environment with a wearable device
First report of Oxalis conorrhiza as alternate host of Puccinia sorghi, causal agent of common rust of Maize
A high genetic variability has been recognized in Puccinia sorghi in Argentina (Gonzalez et al. 2011), although its origin remains unclear since the different reported alternate hosts (Oxalis corniculata L., O. stricta L., O. bowiei Herb. ex Lindl.) have never been detected with this disease in the region. In the spring of 2013 and 2014, the spermagonium and aecial estages of a Puccina sp., were observed on O. conorrhiza Jacq. (syn. O. cordobensis R. Knuth) in Córdoba Province, in central Argentina. Those structures were found in 22 sampling sites, under natural infections, in a radius of 175 km of Córdoba City. O. conorrhiza is a bulbous perennial plant native to South America in the Oxalidaceae family, with a low, moderate growth habit. It is distributed in several provinces of central Argentina. O. conorrhiza can usually be found in alluvial flatlands, riverbanks, wasteland, roadsides, pastures, as well as farmlands. The confirmation of the O. conorrhiza species was carried out by the ACCOR Herbarium of the National University of Córdoba, Argentina. On approximately one-third of the leaves of each infected plant, ampulliform, subepidermal, amphigenous spermagonia, arranged in small clusters of 0.5 mm were observed. Spermagonia containing spermatia and receptive hyphae were golden yellow to orange yellow with abundant nectar exuding. Those in the center of the lesion are surrounded by annular groups of aecia, formed exclusively on the abaxial surface of the leaves. Aecia were orange, cylindrical short, with irregular opening at the apex. To determine the causal organism, aesciospores were inoculated in sweet corn plants. Fifty aeciospores from disease samples were suspended per ml of sterile water and sprayed on 5 sweet corn plants. As a negative control, 5 plants were inoculated with sterile water. All plants were kept in the dark at saturated humidity for 24 h at 24°C. After that, the plants were kept at 25 to 27°C and 70 to 80% humidity with a photoperiod of 16 h light. Seven days after inoculation, typical symptoms of corn common rust were observed: orange uredia with abundant urediospores production. At 21 days, typical teleutospores were observed. The rust matched the morphological characteristics of P. sorghi Schwein (Lindquist 1982). DNA from aeciospores from O. conorrhiza was extracted with NucleoSpin Plant II kit. A fragment from the 28S subunit regions rRNA gene was amplified and sequenced with primers Rust1 and F36 (Kropp et al. 1995). BLAST analysis of 28S sequence data (GenBank Accession Nos. HQ412650.1, GU057994.1, and AY114291.1) showed 99% identity to P. sorghi. To our knowledge, this is the first report of P. sorghi isolated from O. conorrhiza worldwide. The report contributes to an improved understanding of variability of P. sorghi which will be useful for exploring appropriate disease management, epidemiology, and breeding strategies.Fil: Guerra, Fernando Andres.

Identificación de las variables que afectan a la percepción de las transferencias en los viajes multietapa: focus groups en Madrid y Vitoria
[ES] Las transferencias constituyen una etapa esencial en los viajes multimodales, que deben
mejorase para aumentar la eficiencia de las redes de transporte público. Los usuarios tienden
a percibir estas transferencias como una penalización dentro de su cadena de viaje. Por ello,
es importante identificar qué variables influyen en la percepción de las transferencias así
como cuantificar su efecto sobre este fenómeno.
Existe amplia literatura referente a la cuantificación del efecto de las variables que influyen
sobre la penalización de las transferencias; sin embargo, estos estudios no especifican cómo
se han elegido esas variables o por qué. Esta investigación pretende identificar las variables
que afectan a la penalización de las transferencias de modo que los responsables de las
políticas de transporte puedan concentrarse en ellas y conseguir así un uso más eficiente de
los fondos públicos.
Esta investigación se enmarca en el proyecto de I+D+i TRANSFER (Penalización de las
transferencias en viajes Multietapa: percepción del usuario) que ha permitido identificar un
total de 47 variables que influyen en las transferencias, y bajo el que se han llevado a cabo
unos estudios cualitativos en dos ciudades españolas, Vitoria y Madrid, consistentes en
varios grupos de discusión estratificados por edad. A partir de ellos, se han detectado cuáles
son los factores más influyentes en la percepción de la penalización de la transferencia.
Finalmente se ofrecen algunas sugerencias y recomendaciones para los decisores políticos.Las transferencias constituyen una etapa esencial en los viajes multimodales, que deben mejorase para aumentar la eficiencia de las redes de transporte público.

Analysis of energy consumption in Colombia using the holt method
Energy production is constantly facing major challenges today, because despite initiatives to promote the insertion of renewable energy, electricity consumption has shown considerable growth in recent years. In order to use an instrument that facilitates forecasts and predictive processes for the design of strategic plans associated with energy management, the application of the Holt Method is proposed using data on electricity demand in Colombia, GDP per capita and industrial value added, making an analysis of the last 10 years, based on figures from the World Bank. The final results predict that energy consumption for the period 2018-2020 will be between 66,231 GWk and 66,885 GWk

Occurrence of the complete cycle of Puccinia sorghi Schw. in Argentina and implications on the common corn rust epidemiology
The life-cycle of Puccinia sorghi, a heteroecious fungus, consists of five well-defined spore stages. The uredinial and telial stages are completed on the primary host (maize) whereas spermagonial and aecial stages occur on Oxalis spp., a perennial and widespread weed. Portions of corn leaves with telia were surface sterilized and placed in Petri dishes with 2% water agar and maintained in a growth chamber at 25 ± 1 °C and photoperiod of 16 h light and 8 h dark for 48 h to induce the formation of basidia and basidiospores. Oxalis conorrhiza plants were inoculated with those basidiospores, to confirm the generation of spermagonia with spermatia, and subsequently aecia with aeciospores. Corn plants were then inoculated with aeciospores to confirm the formation of urediospores and teliospores. The aecial phase of common corn rust was confirmed to occur on O. conhorriza and the descriptions of spore stages in Argentina are now reported in this work, confirming a potential sexual source of variability of P. sorghi. The natural occurrence of aecial infections on O. conhorriza in Córdoba may play an important role in generating new variants of P. sorghi in Argentina, allowing a constant adaptation of the pathogen to the environment of the different corn production zones.Fil: Guerra, Fernando Andres.
